Copy from wiki :
The EURion constellation is a pattern of symbols found on a number of banknote designs worldwide since about 1996. It is added to help software(Adobe Photoshop etc ) detect the presence of a banknote in a digital image. Such software can then block the user from reproducing banknotes to prevent counterfeiting using colour photocopiers.

This is the Eurion Constellation.

S/W like adobe photoshop, when recognizes this image, they do not create photocopies.

EURion constellation. A pattern of symbols found on banknotes.
Err, but apparently Photoshop and other software do not rely upon this pattern to detect banknotes but rather looks for a digital watermark embedded on the notes.

EURion constellations are found in currency notes and while using image editors like Adobe Photoshop,we find that software refuses to print the image if such patterns are found in image.

The EURion constellation. Pattern of dots with simple geometric structure that most image software and xerox machines can easily recognize and thus refuse to process. Nice question.

Photoshop will disable printing of such images

Though banknote detection code in these applications, called the Counterfeit Deterrence System (CDS),
are supplied to companies such as Adobe, experiments have shown that this banknote detection code does not rely on the EURion pattern.
It instead detects a digital watermark embedded in the images.

EURion constellation. Adobe Photoshop doesn’t print a document that has these patterns.
